GAS-(290K ASSEMBLY.

ToV all ywko/mv t may coa-cera Be it known that ALVIN G. SHERMAN and ALBERT MnADows, citizens of the United States. residing at Detroit, in the countyY of Tayne and State of ll/lichiga-n, have invented certain new and useful Improve ments in Gas-Cock Assemblies.. of which the following is a specification.

This invention relates to av handle assembly, and more particularly to one which is adapted to be secured to the plug of a gas valve used in regulating the flow of gas to the burner of a standard gas range.

llluch difficulty has been experienced. in thepast in the construction of these handles due to the fact that the stove bolt used in securing the handle to the plug backs up on the thread and the porcelain handle becomes loose. It is necessary for the stov bolt to back up only a little in order to loosen the handle. and this difficulty can only be overcome by a frequent use of the screw-driver in tightening the stove bolt.

It is the purpose of our invention to eliminate the possibility of the handle coming loose when the stud that is screwed into the plug` of thel gas cock backs up slightly on its threads. Another purpose of the invention is to provide a special form of screw machine product which can be rigidly se cured within the porcelain handle and can he threaded into the plug of the gas cock by applying the necessary force to an integrally formed nut portion of the screw machine product positioned between the porcelain handle and the plug.

This presents a very neat appearing handle and provides a smooth handle portion, eliminating the: exposedy head of a stove bolt and also provides a construction that can be very easily7 tightened up at dif-- tion of the plug.

Serial No. 674,333.

Fig. 3 is a transverse section taken on the line 3 3 of Fig. 2.

Fig. et is an elevational view of the handle and stud.

Fig. 5 is an end view of the same, showing the angular nut portion for applying a. tool to thread the same into the plug.

The standard `gas cock used on present day gas ranges consists of a barrel c, and a plug Z), which lits into the barrel and is adapted to be rotated to open or close the gas passageway for regula-ting the flow of gas thrfnigh the gas cock. The upper end of the plug I) is provided with a spherical portion 0 provided with a tapped hole (Z for a purpose later to be described.

Our improved handle assembly consists of handle, preferably porcelain, e, provided with a cored hole le use a special form of screw machine product or stud, which is provided with an enlarged nut portion g intermediate the ends thereof and has a tluted portion L on one side ofthe nut which is adapted to be inserted into the hole f carried by the handle. To secure the stud to the handle we cement this stud i. within the hole or recess f, the annular grooves carried by the stud preventing a. longitudinal withdrawal of the stud from out of the handle. will be seen from Vlfig. 2 to Figl 4t. the nut portion ofl thc screw machine product is positioned adjacent the inner end of the handle.

On the opposite side of the nut portion g, of the stud and on the side farthest removed from the handle, there` is a threaded portion z' which is adapted to be threaded into the tapped hole al carried by the plug c. In order to assemble the handle with the plug, the stud z is screwed into the plug and a wrench or other suitable tool is applied to the angular nut portion of the screw machine product to tighten the handle assembly to the plug. It is evident from the foregoing description that the handle portion is rigidly supported on the screw machine product at all times. If the stud z' should back up a trifle on its threads the porcelain handle will not come' loose as is the case with other handles.

We form the handle with longitudinal grooves m in the cored hole f. The purpose of this longitudinal groove it twofold, and it will function not only as an air vent when the cement is forced into the hole and securing the stud therein', but the cement will @from theporcelain and allow the handle to rotate about the stud it it were not `toiI the tongues formed on the cement filler. When a person graspsthis handle, he quite often tends to twist the same and the constant application of this strain is liable to break the union between the .cement and the porcelain it it were not tor the tongue and groove joint between the saine Our'handleconstruetion presents a pleasing appearance to the eye and very neat in construction.` It does not expose any bolt heads to the outside view. The nut portion g can be iiickled so as to Vconform to the nickled surface ot the gas cock. ln the present form ot handle assembly using a stove bolt, the head ot the 'bolt'becomes roughened by continual use of the screwdriver in tightening up the saine, and-often this roughened surface will scratch or cut the hand of the person who is grasping the handle toi' regulating the tiow or" gas to the burner. But in our handle assembly there is no possible chance of a person cutting his hand since there is no break in the smooth contour of the porcelain handle.

What we claim is: y

1.V In a coclrassembly, the combination of a plug provided with a tapped hole, and Y a handle provided with a stud secured therein and projecting from the inner end thereof, said stud provided with an angular mit portionadj acent to the inner end ot the handle, and a projecting threadedV stud portion adapted to be screwed into the said tapped "provided with a recess, and a sci-ew machine Vproduct provided with an angular nnttpoition, and threaded and -giooved portioiis disposed respectively on opposite sides oi the nut portion, the grooved portion cemented within the recess carried byl the handle and the other stud portion adapted to screw into the tapped hole Vol Vthe plug. 3. ln a coclr'assembly, the combination ot a plug provided with a tappe-d hole, fand a handle having a screw iiiacliine product secured therein and provided with an enlarged angular nut portion adjacent the inner end ot the said handle and a projecting threaded stud portion adapted toscrew into rthe tapped hole of the plug whereby the said angular nut portion carried bythe screw machine product is positioned between the handle and the plug.

4. In a lcock assembly, the combination ot Y a plug provided with a tapped hole, handle provided with a recess having a longitudinal groove in the wall formed by said recess,

and a stud provided with an enlarged nut portion intermediate thev ends thereof,v aV

tinted portion onone side of the nut anda threaded portion on the other side ot the nut, the tluted portion ot said stud adaptedto be cemented inthe ygrooved recess of the handle whereby thel cement flows into the longitudinal groove to lrey the handle on the stud to revent relativeV rotatino movement. ot.,

the same.
